Most likely, another possibility is other manufacturers are restricting their motors to a lower rating from the get go, a common thing in my industry is to work to 90% of a piece of equipments rating to improve longevity and reliability.A frisky hill climb at 30% SOC is was the first time in 3 months that my SE throttled the power.
It came in quickly and disappeared quickly.
The motor will have an NTC sensor or whatever buried in the windings I would presume, something's reacting very quickly to thermal load for sure.
The fact that the dealer replaced bowfer's motor and he saw no difference would suggest it's the system's reading of the temp that's going wonky on some cars.
MG could have chosen a motor and chose to run it at it's maximum rating, where as others may throttle from the get go, meaning unless thrashed continuously they wouldn't have to throttle back.
So a fix could be limiting say the 125kW motor to 112.5kW and the 150kW motor to 135kW this would solve alot of the power limiting issues if it is a thermal problem but would reduce over all power.
